OPTICIANS PLIERS- SPECIFICATION forming part of Letters Patent No.764,212, dated July 5, 1904.

Application filed August 8, 1903- .Serial Nol68,750. (N0 model.)

To all whom it may concern.-

Be it known that I, J OHN H. STARBUOK, a citizen of the United States ofAmerica, residing at Pittsfield, in the county of Berkshire and State ofMassachusetts, have invented new and useful Improvements in OpticiansPliers, of-

which the following is a specification.

This invention relates to tools for the use of Opticians, and hasspecial reference to an improved construction of pliers used forapplying the fittings to the lenses of eyeglasses, the object of theinvention being to provide improved pliers for bending together the twoarms of the clips used on eyeglasses, to which the spring which unitesthe glasses is secured or to which when applied to the outer end of theglass the cord may be attached.

The invention consists in mounting a gage plate between the jaws of thepliers, the thick ness of which plate at its periphery varies, wherebywhen a clip is fitted over this plate and squeezed between the jaws ofthe pliers the arms of the clip may be adjusted to fit a lens of anythickness.

In the drawings forming part of this application, Figure 1 is aperspective view of the jaws of a pair of pliers constructed accordingto my invention. Fig. 2 is a side elevation of the same, partly insection. Fig. 3 is a perspective View of a modified form of thegage-plate.

Referring to the drawings, a (0 indicate the two jaws of the pliers,between which on an axis bthere is mounted a rotatable gage-plate 0,preferably circular and whose two sides are located in convergingplanes. At some distance below the ends of the jaws the latter are cutaway, as at (Z, to provide space for the free rotation of thegage-plate. The clip which is to be fitted to the lens is indicated as awhole by c and the two arms thereof which embrace the lens by ff.

Heretofore it has been customary to bend these arms inwardly toward eachother separately by means of small pliers, and it is difficult to bendthem with sulficient accuracy to locate their adjoining sides inparallel planes, and therefore when the screw is put in to bind them tothe glass the latter is not clamped with sufficientfirmness to preventit from turning.

By means of the improved construction described herein the arms f of theclip may be quickly bent together in parallelism and at such distanceone from the other as to cause them to iit'snugly over the edge of thelens.

By applying the edge of the lens to the edge of the plate a it canreadily be ascertained what portion of the periphery of the latter mustbe located between the jaws a to make the arms f fit the lens properlyafter said arms have been pressed together against opposite sides of theplate.

In Fig. 3 is shown a gage-plate having radially-disposed arms 7, whichare of varying thickness and which may be used in place of the circularplate 0, shown in the other figures. The axis on which the plate 0 ismounted is shown in the drawings to consist of a bolt passingtransversely through both of the jaws a, and it may be held in positioneither by a pin /I, passed through it, as shown in Fig. 2, or said bolt,if desired, may be threaded and be screwed into that jaw next the headof the of the bolt. The method, however, of mount ing the gage-platebetween the jaws is immaterial, and other than those means describedherein may be resorted to, if desired.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is

1. The combination with the jaws of a pair of pliers or like implement,of a gage-plate supported between said jaws on a suitable axis and beingfreely slidable on the latter toward either jaw of the pliers.

2. In combination with the jaws of a pair of pliers, a circulargage-plate located between
